A Must-Read for Consultants! What Are Frameworks?

A framework is a “thinking structure” or “analytical tool” for systematically conducting thought, analysis, problem-solving, and more.
In business settings, frameworks are widely used as common templates for organizing complex situations, identifying the essence of issues, and formulating effective strategies. There are many types of frameworks, each designed for specific purposes and situations.

4 Frameworks Consultants Use for Market Analysis

A deep understanding of the environment surrounding a business is essential for formulating appropriate strategies. Here we introduce four representative frameworks for analyzing both external and internal environments from various perspectives.
3C Analysis
3C Analysis is a fundamental framework for environmental analysis used when formulating marketing and management strategies. It is also known as the analytical method proposed by Kenichi Ohmae, former head of McKinsey Japan.
The purpose of 3C Analysis is to analyze the following three elements to clarify a company’s opportunities and challenges in the market.
- Customer
- Competitor
- Company
By understanding customer needs and market trends, grasping the strengths and weaknesses of competitors, and evaluating your company’s management resources and strengths, it becomes easier to develop effective strategies.
SWOT Analysis
SWOT Analysis is an analytical framework for identifying four elements — internal strengths and weaknesses, and external opportunities and threats — to understand the current situation.
- Strengths
- Weaknesses
- Opportunities
- Threats
These elements are organized in a matrix format to consider opportunities to pursue with “Strengths × Opportunities”, threats to avoid with “Strengths × Threats”, challenges to overcome with “Weaknesses × Opportunities”, and areas to consider withdrawing from or scaling back with “Weaknesses × Threats”.
It helps deepen a company’s understanding of its current situation and identify strategic directions.
PEST Analysis
PEST Analysis is a framework for analyzing the macro external environment surrounding a company. It identifies factors that may affect the market and business from four perspectives: political, economic, social, and technological.
- Politics
- Economy
- Society
- Technology
For example, subjects of analysis include legislative changes and deregulation, economic growth rates and price fluctuations, demographic trends and changes in consumer awareness, and technological innovation and infrastructure development.
By analyzing what opportunities and threats these factors may present for your company, you can develop strategies that respond to future environmental changes.
Five Forces Analysis
Five Forces Analysis is a framework for analyzing the competitive structure of an industry and understanding profitability and competitive factors. It was proposed by management scholar Michael Porter.
- Industry rivalry (competition among existing companies)
- Threat of new entrants
- Threat of substitutes
- Bargaining power of buyers (customers)
- Bargaining power of suppliers
The competitive environment of an industry is analyzed based on these five factors. The stronger the force of these five factors, the more industry profitability tends to decline.
By understanding the structural characteristics of an industry, you can gain a strategic perspective for building competitive advantage.

5 Frameworks Consultants Use for Strategy Development

Here we introduce five frameworks useful at the stage of formulating concrete strategies based on the results of business environment analysis. These frameworks are effective when considering market positioning, optimal allocation of management resources, and the direction of new businesses.
4P Analysis
4P Analysis is a framework used for formulating marketing strategies. It combines the following four elements to consider how to deliver value to customers.
- Product
- Price
- Place
- Promotion
By specifically considering what products or services to develop, at what price to offer them, how to deliver them to customers, and how to drive awareness and purchase, you can build a consistent marketing strategy.
Ansoff Matrix
The Ansoff Matrix is a framework for examining a company’s growth strategies. It divides markets and products into “existing” and “new,” presenting the following four growth directions.
- Market Penetration Strategy (Existing Market × Existing Product)
- Product Development Strategy (Existing Market × New Product)
- Market Development Strategy (New Market × Existing Product)
- Diversification Strategy (New Market × New Product)
It is useful for understanding the risks and returns of each strategy and selecting the growth strategy that aligns with your company’s situation and direction.
Advantage Matrix
The Advantage Matrix, proposed by the Boston Consulting Group, is a framework for analyzing the competitive environment of an industry and evaluating the economics of a business. With “number of competitive factors” on the vertical axis and “potential for building advantage” on the horizontal axis, businesses are classified into the following four types.
- Volume business
- Specialized business
- Fragmented business
- Stalemate business
By understanding the characteristics of an industry, it becomes possible to identify the appropriate strategic direction for each business type.
Value Chain
The Value Chain is a framework for breaking down corporate activities into primary and support activities and analyzing how each activity creates value. It was proposed in 1985 by American management scholar Michael Porter.
- Inbound logistics
- Operations
- Outbound logistics
- Sales & Marketing
- Service
- Procurement
- Technology development
- Human resource management
- Firm infrastructure
By visualizing which activities within a company generate added value and where there is room for improvement, it helps with cost reduction, efficiency improvements, and identifying sources of competitive advantage.
PPM (Product Portfolio Management)
PPM (Product Portfolio Management), developed by the Boston Consulting Group, is a framework for companies with multiple businesses or products to consider the optimal allocation of management resources.
Using two axes — market growth rate and market share — businesses are classified into the following four categories.
- Star
- Cash Cow
- Problem Child (Question Mark)
- Dog
It is used for strategic decision-making tailored to the characteristics of each business — whether to continue investing, maintain, or withdraw.

4 Frameworks Consultants Use for Problem-Solving and Organizational Management

Logical thinking and systematic approaches are important for solving various business challenges and effectively managing an organization.
Here we introduce four frameworks useful for everything from identifying issues to executing solutions and analyzing organizations. All of these frameworks are frequently used in driving consulting projects forward.
MECE
MECE (Mutually Exclusive and Collectively Exhaustive) is a fundamental way of thinking for organizing information with “no gaps and no overlaps”. When analyzing complex problems or categorizing elements, it aims for a state where all items to be considered are covered without any duplication.
By rigorously applying MECE, you can accurately grasp the full picture of an issue and prevent insufficient consideration due to gaps or inefficiency due to duplication. It is an important concept that forms the foundation of all analysis and communication in consulting.
Logic Tree
A Logic Tree is a thinking framework that breaks down a single problem into its causes or solutions in a tree structure. Depending on the purpose, there are the following types.
- Why Tree (root cause analysis)
- What Tree (element breakdown)
- How Tree (problem solving)
By breaking down problems into finer elements based on the MECE concept, it becomes possible to comprehensively identify root causes and potential solutions. It is a highly effective tool for organizing complex challenges and visualizing logical thought processes.
McKinsey 7S
The McKinsey 7S is a framework that compiles seven elements necessary for enhancing organizational effectiveness. It consists of the following seven elements.
- Strategy
- Structure
- Systems
- Shared Values
- Skills
- Staff
- Style
These elements are interrelated, and when undertaking organizational reform, it is necessary to consider the alignment of all seven elements rather than changing just one. It is useful when analyzing the current state of an organization and examining the direction of change.
PDCA Cycle
The PDCA Cycle is a continuous management method that aims for business improvement and goal achievement by repeating four stages: Plan, Do, Check, and Action.
By cycling through making a plan, executing it, evaluating the results, finding areas for improvement, and connecting them to the next action, you can achieve continuous quality improvement and operational efficiency.
It is also a framework used in consulting projects for verifying the effectiveness of proposed measures and the improvement process.

What Are the Benefits of Consultants Using Frameworks?

There are many benefits for consultants in using frameworks. Let’s look at the reasons why consultants use frameworks.
Organizing Information Makes It Easier to Identify Issues
Using frameworks allows you to structurally organize complex, intertwined information.
For example, using 3C Analysis or SWOT Analysis makes it possible to classify various information about the market, competitors, and your own company, and clearly understand the relationships between each.
As information becomes organized, the essence of previously hard-to-see issues and the root causes behind problems become easier to identify. You can accurately pinpoint the issues that truly need to be resolved — not just surface-level problems — and build a foundation for considering effective approaches.
Easier to Establish Shared Understanding Within a Team
Frameworks provide a common thinking structure among project members.
For example, sharing analysis results using the same framework minimizes discrepancies in the information and understanding held by each member. As a result, the efficiency of discussions improves, and it becomes possible to reduce misunderstandings and rework.
By using frameworks to explain things clearly to clients and deepening their understanding of proposals, it becomes easier to form a shared understanding. The use of frameworks is a very important element in smoothly advancing a project.
